Hi.
I am new to reefkeeping and i set up a 15g tank.
I got live rock,and i saw these on one part of the rock.I dont know what these are,if they are good or bad.....
Could you please help me...

Second photo looks like some upset corals (maybe zoas) = good
Third, maybe a sponge = good - if it dies off it will start your cycle strong

Looking nice! You have some serious power heads in there it seems.

Those are the skeletons of hidden cup corals. Phyllangia americana.

those are different type of algae. should die off if nutrients are low....also. your tank could use some more water in it too.
